PHP

Strict types, explicit contracts, no magic. If a class needs a docblock to explain what its properties do, the properties are named wrong.

PHP 8.5+ is the baseline. Use modern syntax unconditionally — union types, enums, readonly classes, property hooks, named arguments, match, pipe operator. No backward compatibility with older PHP versions unless the project explicitly requires it.

Every PHP file starts with declare(strict_types=1).
